0128050LuccaThis award supports Don Lucca and students from the Oklahoma State University in an extensive collaboration with the universities of Aachen and Bremen in Germany. The project will focus on discovering what factors are generating the new wave of high-tech The resulting U.S.-Germany Transregional Collaborative Research Center involves sixteen technical projects centered on the development of processes for the manufacture of complex, high-quality optical components for next generation applications in information technology and telecommunications, health care, the life sciences, sensing, lighting, and energy conversion. There are technical projects in the areas of deign, had coatings, replication techniques, and measurement science and technology. Funding for this long-term research center, with the exception of the project here described, is being supplied mainly by the Deutsche Forschungsgemeinschaft, the German counterpart to NSF. The research focus of the U.S. project, "High Resolution Surface Zone Analysis," is the investigation of the near-surface mechanical nature of sol-gel derived diamond-turnable, hard mold coatings which will be used in the volume production of ultraprecision optics of polymers and glasses. Nanoindentation will e used to study the near-surface mechanical properties including elastic modulus and hardness, and the surface residual stress state of the hard coatings. Depth profiling studies will e performed on cross-sectioned and taper-sectioned coatings with a newly developed method for near surface zone analysis. The adhesion and delamination behavior of the mold coatings will be explored with the use of nanoscratching. The project will also further contribute to the development of advanced surface characterization tools needed for assessing the near-surface mechanical state at the nanometer scale.

0128050卢卡这个奖项支持唐卢卡和学生从俄克拉荷马州州立大学在一个广泛的合作与亚琛和不莱梅大学在德国。 该项目将侧重于发现哪些因素正在产生新的高科技浪潮。德国跨区域合作研究中心涉及16个技术项目，重点是开发用于信息技术和电信、医疗保健、生命科学、传感、照明和能源转换等下一代应用的复杂、高质量光学元件的制造工艺。 在设计、热喷涂、复制技术和测量科学与技术方面有技术项目。 除了这里所描述的项目之外，这个长期研究中心的资金主要由德国研究共同体提供，德国研究共同体是国家科学基金会的德国同行。 美国项目“高分辨率表面区域分析”的研究重点是研究溶胶-凝胶衍生的金刚石可转动硬模涂层的近表面机械性质，该涂层将用于聚合物和玻璃的超精密光学器件的批量生产。 纳米压痕技术将用于研究硬质涂层近表面的力学性能，包括弹性模量和硬度，以及表面残余应力状态。 采用新开发的近表面区分析方法，对横截面和锥形截面涂层进行深度剖面研究。 模具涂层的附着力和分层行为将与纳米划痕的使用进行探讨。 该项目还将进一步促进开发评估纳米尺度近表面机械状态所需的先进表面表征工具。
